Enhanced PWM Modules

The 2833x/2823x devices contain up to six enhanced PWM (ePWM) modules (ePWM1 to ePWM6). Figure 8-4 shows the time-base counter synchronization scheme 3. Figure 8-5 shows the signal interconnections with the ePWM.

Table 8-4 shows the complete ePWM register set per module and Table 8-5 shows the remapped register configuration.

GUID-AAC3E846-5DEF-4971-A89E-A258D55881DD-low.gif
By default, ePWM and HRPWM registers are mapped to Peripheral Frame 1 (PF1). Table 8-4 shows this configuration. To re-map the registers to Peripheral Frame 3 (PF3) to enable DMA access, bit 0 (MAPEPWM) of MAPCNF register (address 0x702E) must be set to 1. Table 8-5 shows the remapped configuration.
